Limitations
• The BladeCenter HS23 contains 16 DIMM sockets.
A maximum of 256 GB of system memory is supported by using a 16 GB DIMM
of ECC DDR memory in each of the DIMM sockets.
A minimum of one DIMM per CPU must be installed; DIMMs may be added singly
after that. DIMMs must be installed in matched pairs for Mirror Mode.
Refer to the Planning information section or the System x server website for
memory options.
• Microprocessors must be of the same type, power level, and clock speed on each
BladeCenter HS23. Mixing microprocessors of different speeds, power levels, or
cache sizes or upgrading the base processors is not supported.
• Not all microprocessors are supported in all chassis. The latest BladeCenter
hardware and software compatibility is available at
http://www.ibm.com/servers/eserver/serverproven/compat/us/
• The new IBM BladeCenter HS23 is supported in the BladeCenter H chassis
(#8852), the BladeCenter HT chassis (#8740, 8750), the BladeCenter E chassis
(#8677), and the BladeCenter S chassis (#8886).
